Eight Years Later
Karan and Kaien were growing like weeds. They didn't stay in the hideout for long. Madara died of old age and it was time to move on. Zetsu and Obito went along with the plans Madara left for them. They found Nagato and Konan, and got them on board with the plan. Obito and Zetsu left the twins in their care until they were old enough to start training.
At the age of four, they were taken to a small home in the country, out of the eye of anyone that would ask questions. There Obito started training them. The training was brutal on the kids but they endured and grew stronger. By the age of five both of them could use the Uchiha Clan's Great Fireball Jutsu.
Both of the twins were gifted but of the two Karan was more advanced. Along with mastering the Fireball Jutsu, she also mastered the Phoenix Flower Jutsu, and the Shadow Clone Jutsu. This was in part due to her gift in Chakra Control. She had also taken an interest medical ninjutsu. She hadn't had much luck there but was very good administering first aid treatments since she had a lot of practice with Kaien.
Kaien had more of a hard time, but that did not stop him from trying. He believed that as the older sibling it was his responsibility to protect his sister. He trained every hour of everyday and he reaped the rewards. The siblings were inseparable. When Obito tried to punish Kaien, Karan would take the blame to protect her brother and Kaien would do the same for his sister. Obito would come and go leaving the twins under the supervision of white Zetsu, which pretty much equaled no supervision.
One day, as the twins were taking a break from training Obito appeared but not alone. The kids were playing until they heard the calls of the one person they were never happy to see. Their joyful smiles disappeared and were replaced by grim frowns.
"Kaien, Karan, come here now," he said sternly.
The twins turned to look at each other and gave each other a nod. They held each other's hand and walked to their caretaker, getting ready for whatever mood he may be in.
"Have you been training?" He said looking at them.
"Yes, sir." They answered at the same time.
"Good, its time to start the next step of your training. It will be harder than before. I don't have time to oversee this so I brought someone who can. Itachi will oversee your training from now on. You will do as he says or will be punished, is that understood." He said as the twins bowed they're heads.
"Yes, sir" They answered.
Itachi just watched the interaction between the three. Madara asked him to join his organization the Akatsuki, after leaving Konoha. He said he needed time before presenting him to the other members. In the meantime he had a job for him, training two of the organizations wards, he had said to describe them. Looking at them now he wondered where they had come from. The children shared a lot of similar features, from their eyes and nose, to the way they walked.
The girl reminded him of someone but he didn't know whom. She had dark eyes just like her brother. She had short brown hair that was loose in a short chin length bob. She wore a purple kimono dress with short tights under and black ninja sandals.
Her brother wore a short sleeve black tee shirt with a red hoodie and white shorts and black ninja sandals as well.
"I'll leave you to it." He said vanishing.
The twins looked relieved that he was gone but still concerned with the stranger standing in front of them.
Itachi decided to break the silence by staring off the same way his sensei back in Konoha had.
"How about you two introduce yourselves. Start with your names, likes, dislikes and goals." Itachi said.
Kaien and Karan turned to look at each other and had a silent conversation with their eyes.
'Is he serious?" Kaien thought.
'The way he's looking at us I'd say he is.' Karan thought.
'Do we answer honestly' Kaien asked.
'Well you did hear him, do as he said or else.' Karan said giving him a glare.
'Twin act then' Kaien thought with a smirk.
Karan just nodded at that.
'They seem to get along well enough' Itachi thought.
"I'm Uchiha Kaien." The boy introduced himself surprising Itachi.
"I'm Uchiha Karan" The girl said next. Itachi had a hard time trying to contain his surprise.
"I like swimming, running, and the color red." Kaien said slightly smiling thinking about it.
"I like reading, the stars and the color blue." Karan said smiling politely.
The twins got quiet. "Any dislikes?" he said wondering why they got quiet.
"Madara." They both answered at the same time.
"And goals." He asked.
The twins just looked at him confused.
"Goals, like what we want for our future?" Karan asked.
"Yes." Itachi said observing them.
"Don't know." Said the boy with a shrug.
"Same." Said the girl.
"Then what are you training for?" Itachi asked them.
"To get strong enough to protect my sister." The boy said.
"To be able to protect my brother." The girl answered.
"Then that's your goal." Itachi said.
"What about you? Are you going to introduce yourself?" Kaien said making his sister glare at him.
"My name is Uchiha Itachi, I like tea and dango, I dislike… certain people, and my goal is to protect someone I care about." Itachi said looking nostalgic, thinking about his brother who is the same age as the children sitting in front of him.
'I wonder who that person is, he looks sad.' Karan thought.
"Since I'm now in charge of your training I want to see where you're at so you two are going to spar. No weapons, just taijutsu and ninjutsu. Match ends when someone pins the other or someone gives up." He said.
Karan and Kaien stood up and got ready. They made the union symbol and waited for Itachi to say go.
As soon as he did, Kaien ran to tackle his sister but she dodged him at the last minute. She then tried to kick him and he managed to block it. He took advantage to try and knock her down with a punch but she had used the substitution jutsu.
'Where did she go?' Kaien though as he started looking around.
Then from above a tree she jumped down and tried to land a hit but he managed to jump out of the way.
'Taijutsu isn't working, Kai can read my moves too fast for me to land any hits' Karan thought.
"Time to stop holding back Kar." Kaien called out.
"Was about to say the same thing." Replied Karan.
The twins jumped up and started making handsigns. They were so fast Itachi had to activate his Sharingan to be able to tell what they were going to do.
"Fire Style: Giant Fireball Jutsu" They both yelled out at the same time.
'For someone at that age to have enough chakra to pull off a jutsu of that size after using a substitution technique is rare. She must either have massive massive chakra reserves or great control.' Itachi thought.
The fireballs met and blasted both of them in opposite directions. Kaien landed in the lake nearby and Karan against a tree.
Itachi looked at both of them and realized they were near their limit. 'Now might be a good time to end this' He thought but before he could do anything he heard Kaien yell out "Water Style: Giant wave vortex." And a giant wave went to go attack Karan. The wave crashed against her and she was knocked out. She was on the ground not moving. When Kaien walked closer to check on her, something grabbed his leg and pulled him down.
"Earth Style: Head under Jutsu." Karan Said pulling her brother down.
"But how?!" Kaien said confused. He turned to look at where he thought his sister had been and saw the shadow clone disappear.
"Shadow clone? No fair Karan, you know I still can't do that one yet." Kaien complained trying to free himself.
"You used the giant wave knowing I can't swim. Serves you right." Karan retorted panting.
"That's enough you two." Itachi said ending the fight. "Karan won the match, never expect your opponent to play fair they'll find a weakness and won't hesitate to use it against you. Now unbury your brother." She told Karan.
She started to dig Kaien out but as she started walking to him she fainted. As she was falling Itachi caught her.
"Nee-chan!" Kaien said somehow managing to free himself and running to his sister's side.
'She used too much Chakra. Her limits are beyond what I expected for someone her age' Itachi said looking her over.
"What's wrong with her Itachi-san?" Kaien said worried.
"She used too much Chakra in the fight. She just needs rest." He said picking the girl up. "Let's go back to the house, She needs rest. And it's getting late, I'll start on dinner."
"Okay" said Kaien following him.
'Why did he ask me to train these two? They are more proficient than any genin I've seen. They could probably be ranked at Chunin or higher' Itachi thought.
After putting Karan on her sleeping mat, he started making dinner. He made some stir-fry and rice. He was surprised when Karan woke up and had dinner with them despite the fact that she should have been passed out until the next morning. They were quiet at dinner and were careful about anything they said in front of him. After dinner they each cleaned their placemat and thanked him for dinner before heading off to bed.
Itachi went outside to get some air and think about everything that happened that day.
At that minute he felt Madara materialize next to him.
"How was training?" He asked already knowing the answer.
"Why did you ask me to train them? They are more than advanced enough to perform missions." Itachi said.
"Something bothering you?" Obito said with a smirk under his mask.
"Uchiha Kaien and Karan" he said "How?"
"Synthetic fertilization and implantation in a surrogate. One of the techniques Orochimaru developed before abandoning Konoha."
"They're biological father by donation was an Uchiha." He said almost angrily clenching his hand in a fist.
"The girl, she reminds me of someone I've seen before." Said Itachi, still wondering from where though.
"That's not important, Train them to the best of your abilities, which I know is far superior the level those brats are currently at." Obito said.
"Why do you need them, you have the Akatsuki?" Itachi asked.
"I don't need them specifically, I need their Sharingan." Said Obito teleporting away.
